LOOM-CONTROLLING MECHANISM.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed February 1, 1917. Serial No. 146,027.

levers or other corresponding elements are y actuated and controlled by the coperative action of a plurality of pattern cylinders.

Such a mechanism is shown in my prior Patent No. 1,179,423 issued April 18, 1916, and my present invention relates to certain improvements in the loom controlling mechanism or multiplier therein shown.

It is the object of my present invention to provide a mechanism of this type which is particularly adapted for Weaving blankets or other fabrics in which two weaves are found, one Weave commonly forming the body portion of the fabric, and the other weave being used for the border or heading of the separate articles successively woven in the fabric. For the attainment of this object I provide two actuating cylinders which jointly control and actuate the indicator levers through which the drop boxes or other loom mechanism is y controlled. Thos@ actuating cylinders are operated independently of each other, and neither cylinder is in any way controlled by the other cylinder.

In addition to the actuating cylinders I provide two multiplying cylinders each of which may he put in operation by either actuating cylinder. A multiplying cylinder thus put in operation, after completing one run of its multiplying chain or pattern, will always restore control oi the mechanism to the particular actuating cylinder by which the multiplying cylinder was started.

In addition to the actuating and multiplying cylinders above described, Iy also provide a control cylinder elfective to determine which actuating cylinder'shall operate, thus governing the sequence of the wcavesin the fabric. This kcontrol cylinder may also be used as a multiplier to cause a repetition of the entire pattern carried by either actuating cylinder.

While the broad features of my invention have been set forth above, my invention also consists in certain arrangements and combinations of parts Whichwill be hereinaitcrY described and more particularly pointed out in the appended claims.

The preferred form of my invention is Vshown in the drawings in which- Figure 1 is a 'plan view of my improved controlling mechanism or multiplier;

Fig. 2 is a sectional side elevation taken along the line 2-2 in Fig. 1;

Fig. 3 is a similar Sectional elevation taken along the line 3--3 in Fig. 1, and

Fig. 4 is a diagrammatic plan view of the Ydifferent pattern cylinders.

Referring to the drawings, the controlling or multiplying mechanism is mounted in side frames 10 and 1l connected by horizontal members or cross 1girts 12 (Fig. 2) to an upright stand 13 by which thc mechanism may be secured to the loom frame. The side frame members 10 and l1 are also connected to each other by cross rods 14, 15, 16, 17

and 18 (Fig. 2) to which the members are Y secured by set screws 19 (Fig. 1).

In the frame work thus constructed I mount tive pattern cylinders A, B, C, D. and E. The cylinders A and B are termed the actuating cylinders as they directly control the operation of the indicator levers 20 and 21 which in turn control the drop boxes or other loom mechanism connected thereto. The levers 20 and 21 ovcrlie thc actuating cylinder A and are directly operated by pattern rolls thereon. The levers 20and 21 are provided with extensions 20*l and 21, said levers and extensionsA being rigidly connectedV through intermediate portions 2Ob and 21", each lever, extension and intermediate portion forming a single pivoted structure loosely mounted upon the cross rod 14. The extensions 20il and 21a ovcrlie the actuating cylinder B and are operated by pattern rolls thereon.

The cylinder A is fixed to a shaft 22 (Fig. 2) having a bearingin the member 10 of the multiplier frame. A hand Wheel 23 (Fig. 1) secured to the shaft outside of the side frame 10 provides'means for manually setting the cylinder A.Y The actuating'cylin- 'der B is freely rotatable upon theY shaft 22 Vtins 36land46, and thus cont yas 'rio over reg @serene e or 'cylinder are concerned.

"arm 1l-Band thus raise the 57i! f 'control these levers engaging arms 36 and 46 respectivelyV on the rockers 35 and 45 and thus controllingV the" feedlof Y the actuating cylinders A and B. 4A single lever BTO-overlies the roll d ofthe multiplying cylinder D, but this lever is formed with its Weighted end of double v'vlidtV *sothatit engages two projecl rols the feed of Both i 'lridrsilrand E and alsoicontrols tvfoactuating eylrfdersniandf.

c `constrluictionV offmy improve Y controlling Vmechanisrr`for multiplier, I will now point out its method of operation. In Fig. l'I haveshown the rolls on the several pattern Vcylinders in Ysuoli a position" thatV gtlhecylinders B, D and E are inoperative and thezli der .is` about to multiply the combination called for'by the cylinderA. nIt will Vhefneted"that'thr' cylinder B lis stopped withrollsr'fand binnderlyingthe Weighted lver'si'i?, 57 and Y The rockers 55,A 65 `anddherrock shaft 75'are thus released by the cylinderrB, and the shields 54, 64 and 74 for the'cylinders C, D and E are free to drop, so far as the weighted levers actuated by the'cylinder B It will also be noted that no roll b isoperativelyipositioned, so that the indicator levers 20 andi VEfira-ri be freely ra'ised or'lovvered bythe rolls c on the cylinder A. Thscornbnationof rolls is YValways used on thev cylinder or B-iat Vthe point at which the pattern Vis completed andthe control is to be shifted to the other 'actuating cylinder.

This shifting of the control is determined der E which is sh own in Fig. lever 37, thus lever 47 permits this lever an shield 44 er the feed pawl 40 inoperative. W Y AOnithe cylinder @Ajtle'rolls mayY be placed as desiredtogrve'the desired' Inove- -ments to the indicator levers 20 and 2l. In the position shown in the drawings, a roll a underlies theflever'Q which is raisedtherealsoY underliesY Vthe t lever 57,

of the multil'ingncylinder Oristhe lever by cylinder @Bicis f' also raised, the s hield 54 will'flji'aiadthe"cylnder fviille Vstarted at the next movement of the actuating arm 29". The first advance movement ofthe `-cylinder"Gfvvill remove the roll c from beneath the lever 470 andthis lever will then rest upon projections 36 and 46 of the rockers 35 and 45, thus holding both feed pawls 3() and 40 out of operation until the cylinder has completed its series.

Each multiplying chain is formed of a Y the dtails herein single pattern roll VVtheflever470, releasingthe pawls 30 and 40.

The' pavvl 40 will befstill 'heldvfrom opera- Aticnhy the levrfl controlled by the cylinderuE5lout the pawl 3() Will be free to feed the cylinder A'fo'rvva'rd onestop.

In' the combination` show-n in the drawing, the next'movementofthe chain upon the cylinder A will place'thevroils a', ai andas under the levers 67, 57 and 77 and Will omit rolls e under the indicator levers. All of the Weighted levers which control the cylindei's C', Dfand E are therefore raised, and all ofthefe'ed pavvvls 5G, 60 andl7() would become Vrsirnultaneou sly'roperativeY if it were notYV for the'anxiliary hields i540 andV 640. As the levers 77 and 7 7 b are raised from the armsI 76- the fcountervveightsY 76 will move theja'oclr :shaft 7 5, raising the auxiliary shields 540 and 640 and depressing the shield 74. The pawls 50 and 60 are thus rendered inoperative by the auxiliary shields, and the pawl is alone operative toadvance the cylinder E. Such advance movement in the direction of the arrow Awill remove the roll effrom beneath the lever 37 and will cause Va Vroll 'ertoraise the lever 47. Y The Vlever 37 veillren'der the pawl 30 and 'cylinder A in- 'nperativa' and the raising of the lever 47 will permit the pawl 40 to actnate the cylinder B. Upon the next forward movement of the cylinder B a roll b will raise the :lever V67, thus releasing the pawl 60 and causing the multiplying cylinder D to operate.

It will be noted thatthe `multiplying cylinders always stop withrolls under the levers '370ant 2470,' thus' leaving Ithe pavvls 30 andllinndei' theeontr'l ofthe cylinder E.
